Centos 7.5 blank screen on boot after update/install

[adnan]

Hello

After updating or doing a fresh install or update I get a blank screen. No prompt or anything. At times I have noticed the login prompt appear after a few minutes. The system works fine, as one can ssh into it, but cannot see the screen.

Have you previously installed proprietary video drivers from e.g. nvidia or AMD or VMware? If so then, when using their binary drivers, it is necessary to reinstall them every time the kernel is updated and you reboot into the new one.

For nvidia, it's possible to use the kmod-nvidia* packages from ELRepo and these do survive most kernel updates. If you want to use them then google for ELRepo, install their elrepo-release package then install nvidia-detect and run it. It will tell you which of their kmod-nvidia* packages you need to use for your video card.

Hello
I have not installed any driver. I don't think the server even has any Nvidia graphics card. These are the Dell node servers.

Any help would be appreciated. That nvidia-detect does not find driver that can be used.

According to lspci the video card is Aspeed and driver is ast.
